Purpose:
This study investigated the microbiological profile and clinical characteristics of culture positive (CP) contact lens-related bacterial keratitis (CLBK) and compared them to culture negative (CN) cases.
Methods:
We retrospectively analyzed 142 CLBK patients hospitalized between January 1998 and December 2022. The CP and CN groups consisted of 79 eyes (100 isolates) and 63 eyes, respectively. We investigated the microbiological profile in the CP group and compared the epidemiology, predisposing factors, clinical characteristics, and treatment outcomes between the CP and CN groups. Poor treatment outcomes were defined as a final best-corrected visual acuity (BCVA) ≤ 0.5, worsened BCVA after treatment, or the need for surgical intervention. We evaluated the risk factors for poor treatment outcomes in the entire cohort through two-proportional Z-test analysis.
Results:
In CP group, gram-negative bacteria accounted for 85%, and common isolates were Pseudomonas (27%) and Serratia (26%) species. There were significant differences in mean age (27.0 years vs. 33.8 years, p = 0.009) and a history of therapeutic bandage contact lens wear (13.9% vs. 28.6%, p = 0.031) between the CP and CN groups. However, there were no significant differences in symptom duration, prior use of topical antibiotics, sleeping with wearing CL, epithelial defect size, hypopyon, and poor treatment outcomes. Significant risk factors for poor treatment outcomes in the entire group included deep infiltration (Z = 2.88), epithelial healing time ≥ 7 days (Z = 2.30), initial BCVA < 0.1 (Z = 2.20), over date use of contact lens (Z = 2.10), and epithelial defect size ≥ 5 mm2 (Z = 2.05).
Conclusions
There were no significant differences in clinical characteristics and treatment outcomes between the CP and CN groups. Poor initial clinical findings and over date use of contact lens were associated with poor treatment outcomes in both groups. J Korean

Benign pulmonary tumors are rare entities, and among them bronchial lipomas are the most uncommon. Up to date, about 80 cases have been reported in the English literature. But, the bronchial lipoma with extrabronchial growth causing middle lobe syndrome and pneumonia is extremely rare. Bronchial lipomas, mainly arising from normal fatty tissue of the proximal portion of the lobar or segmental bronchi, are histologically benign. But if diagnosis and treatments are delayed, they can produce extensive pulmonary parenchymal damage and irreversible brochiectasis distally. So whenever possible, the treatment of choice is resection by means of bronchoscopy via early diagnosis. But if endoscopic removal is not possible because the distal end of the tumor could not be visualized by fiberoptic bronchoscopy or if the nature of the tumor is unclear, surgery is necessary, with lobectomy or pneumonectomy being required in most cases due to the extensively damaged pulmonary parenchyma. We present a case of bronchial lipoma with extrabronchial growth, with a review of the literature and report of an unusual case.

OBJECTIVES: The Beck Hopelessness Scale (BHS) is a 20-item scale for measuring the extent of negative attitudes about the future. Previous studies repeatedly demonstrated clinical utility of BHS, particularly for predicting suicide. The aim of this study is to examine the reliability and validity of the Korean version of the Beck Hopelessness Scale (K-BHS), which is commonly used for measuring hopelessness. METHODS: The study sample consisted of 1022 community-dwelling general adults from 4 regional areas (i.e., Seoul, Gyeonggi, Cheongju, and Jinju) across South Korea. They completed the K-BHS, Patient Health Questionnaire-9, Spielberger State-Trait Anxiety Inventory, and Adult ADHD Self-Report Scale. RESULTS: The Cronbach's alpha value for the K-BHS was 0.85. Test-retest reliability at average 7.2 days was 0.86. Discriminant validity was determined. Confirmatory factor analysis supported a three factor model. CONCLUSION: The K-BHS demonstrated satisfactory reliability and validity and therefore may be useful in measuring the construct of hopelessness and in clinical suicide risk assessments. Further studies are needed in order to explore the psychometric features and correlates of this scale among clinical populations.

We have always attempted to create a standard treatment protocol for patients with gastric cancer. However, many debates still exist regarding gastric cancer treatment. For the past 2 years, at the Annual Congress of the Korean Gastric Cancer Association, we have presented a grand symposium on the "Debates on the strategy for treating gastric cancer". In 2008, four major topics were discussed and voted on after discussion. The four major topics were proximal location treatment for early gastric cancer, management choices for pyloric obstruction with advanced gastric cancer, management of liver metastasis, and reconstruction methods after a distal gastrectomy. The opinions of the audience for six minor topics were expressed by an electronic voting system. In 2009, the four main topics were treatment for submucosal tumor sized around 2 cm, laparoscopic gastrectomy in T2N1 gastric cancer, choices for managing gastric lymphoma, and application of a pylorus preserving procedure for early gastric cancer at the antrum. The opinions of the audience for these six minor topics were expressed by an electronic voting system, as was conducted in 2008. It was good opportunity to identify a point of contact about the debates on managing gastric cancer. The results of these debates and studies will identify the best methods to treat patients with gastric cancer.
